Calculation method
Calculation method
Branch currents (A)
For each resistance R in b: branch current = a × (1/R) / sum of all reciprocal resistances.
Symbols and units
- a
- Total current (A)
- b
- Parallel resistances (Ω)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Current divides in proportion to branch conductance. Lists support up to 1,000 finite values.
